Answer:
(a)
Haloarenes are less reactive towards nucleophilic substitution because the
benzene ring in haloarene is electron rich, also it withdraws
electrons from chlorine. Hence benzene becomes more rich in electrons and favor
electrophiles to attack it in comparison to nucleophilic attack is
easy.
(b) being a
stronger nucleophile than , the
later cannot displace the former.protonates
ROH' to form being
a weaker nucleophile than , it is
easily displaced by latter. 1
